Horsepower was originally measured and calculated by use of the "indicator diagram" (a James Watt invention of the late 18th century), and later by means of a Prony brake connected to the engine's output shaft. Assuming the third CGPM (1901, CR 70) definition of standard gravity, gn = 9.80665 m/s2, is used to define the pound-force as well as the kilogram force, and the international avoirdupois pound (1959), one mechanical horsepower is: Or given that 1 hp = 550 ft⋅lbf/s, 1 ft = 0.3048 m, 1 lbf ≈ 4.448 N, 1 J = 1 N⋅m, 1 W = 1 J/s: 1 hp ≈ 746 W. The various units used to indicate this definition (PS, KM, cv, hk, pk, ks and ch) all translate to horse power in English. Drawbar horsepower (dbhp) is the power a railway locomotive has available to haul a train or an agricultural tractor to pull an implement. [25][26] The RAC formula was sometimes applied in British colonies as well, such as Kenya (British East Africa).[27]. [23], Boiler horsepower is a boiler's capacity to deliver steam to a steam engine and is not the same unit of power as the 550 ft lb/s definition. Correction factors are used to adjust power and torque measurements to standard atmospheric conditions, to provide a more accurate comparison between engines as they are affected by the pressure, humidity, and temperature of ambient air. All the above assumes that no power inflation factors have been applied to any of the readings. [9][better source needed] Engineering in History recounts that John Smeaton initially estimated that a horse could produce 22,916 foot-pounds (31,070 N⋅m) per minute. [21] Tax horsepower ratings were originally more or less directly related to the size of the engine; but as of 2000, many countries changed over to systems based on CO2 emissions, so are not directly comparable to older ratings.
